I know, that was my reaction at first too. But I tried it for a month and honestly it’s an amazing search engine. If it helps you to know, when you search they also use the (paid) search APIs of other search engines and aggregate the results in a way to get something better than any individual engine - so your searches actually have a decent marginal cost for them.
I suppose I can technically answer this. I do use Linux full-time now and have for several years, but prior to that I had a few false starts where I’d switch back to Windows. Usually it was because I’d encounter some technical issue I just didn’t know how to fix besides reinstalling the whole OS, or a graphics driver issue. For example, at one point when I had an NVIDIA graphics card only the newest drivers from NVIDIA’s website supported it but the ‘stable’ drivers in Ubuntu’s repo didn’t, so I had to manually install the drivers. Except then whenever the kernel was updated by Ubuntu (basically every week) my display stopped working and I’d have to switch into a TTY and manually reinstall the drivers.
Now I know how I’d fix that (setup some rule to reinstall the drivers whenever the kernel updates, which I believe is now the default anyway), or use a PPA containing the latest NVIDIA drivers, or use AMD instead - but really any kind of problem that requires the user to both diagnose and fix the issue prevents non-technical people from adopting it.
I’ll just mention my own experience. I struggled with depression and/or anxiety for basically my entire life from as early as I can remember and I definitely didn’t have the kinds of joyful childhood experiences you describe. However now that I’m older and my anxiety is being properly treated (medication) I’ve definitely had more / stronger feelings of joy with simple experiences. All this is to say that I think it might be a depression thing, not a age thing.
Ehh it's testing the kids to see how much they learned of the racism Chinese people faced on the West Coast (North America) back then. It's also a good way to have students emphasize empathize with those experiences too by making them write from that perspective.
